This is a common net configuration often used by the USGS and other government agencies. This net is designed to collect veligers, the free-swimming larval form of Zebra and Quagga mussels (Dreissena spp.) As we all know, these fast-spreading invasive species has been taking over our lakes for a number of years. Because they reproduce so quickly and in such dense configurations, they are interfering with the food chain of our native species and can be easily and inadvertently transferred from lake to lake on boats, nets and clothing. Keeping track of - and curtailing the spread of - veligers has just become easier with the Wildco® Veliger Net. Our net is extra-long, with a 20-inch mouth opening and hefty, 1000mL collection bucket. The extensive volume of water sampled with this net is needed to calculate the veliger density using microscopic methods in the laboratory. And, because, like all Wildco® nets, it is impeccably well-constructed, it can withstand the constant decontamination procedures involved with sampling these organisms. The 33-E28 Veliger Net comes complete with the following Wildco® net configuration: • 31-E28-1:4 Plankton Net, 1:4 ratio (20" opening, ~80" long), 63µm mesh • 7-E50 Ring & Bridle 20" (500mm) • 48-D80 Dolphin Bucket Adaptor, 3.5" • 47-F28 Dolphin Bucket, 1000ml, 61µm stainless steel mesh • 47-F99 Guard Rails for Dolphin Bucket NOTE: This configuration can be altered or customized to meet your specific needs, please call or e-mail us with your requirements. Click the accessories link to the right to complete your sampling package: We recommend that a flow meter be attached to the net and that the net be towed slowly. The distance of the tow should be recorded. A line depressor can be used to keep the net at a desired depth since the veligers tend to be found in deeper areas.
